Smoke Sealing Systems
Fire Rated (Labelled) Doors
Fire doors in Australia need to be installed to AS/NZS1905.1 as mandated by the NCC. This means the fire door has a Fire Resistance Level (FRL) as determined in the fire test method AS 1530.4 where door sets are subject to extreme temperatures in a full scale fire test simulating a fire emergency. The door set is then given an FRL which is a nominal grading period in minutes for structural adequacy/integrity/insulation. Fire doors are not structural members of a building so therefore have for example an FRL of -/120/60 where the FRL is 0 for structural adequacy/120 minutes for integrity/60 minutes for insulation. This is represented in NZ as FRR -/120/60 or in the UK for integrity as FD120 or in Europe IE120.
Door hardware including door seals are then tested to evaluate there is no reduction in the established FRL of that fire door.
Effective combinations of smoke and acoustic seals for fire rated butt hinged doors that have been tested and/or assessed to AS 1530.4 and BS 476 Pt. 22 (similar to BS EN 1634-1). These seals meet the requirements for AUS NCC S12C4 Construction Deemed-to-Satisfy for smoke doors, NZ BC Compliance Doc. C, UK Approved Document B and standard BS 5588.These systems meet the leakage rates specified in AS 6905 when the door assembly is installed to AUS NCC NCC S12C4 Construction Deemed-to-Satisfy for smoke doors. Meets leakage rates specified in BS EN 13501-2 "Sa", "Sm" classification.
These systems have been smoke leakage performance tested to:
AS 1530.7 ≤ 25m3/h @ 25 Pa when exposed to 200°C > 30 minutes in accordance with AS 6905.
EN 1634-3 ≤ 3m3/h/m @ 25 Pa for ambient and ≤ 20m3/h @ 50 Pa for medium temperature in accordance with BS EN 13501-2.
A large range of product combinations may be used, refer to door bottom seals and door frame or perimeter seals sections for fire ratings of individual seals.
Threshold Plates in Sealing Systems
Aluminium threshold plates can be used under a fire door when the
gap exceeds the specifications of the door bottom seal or to provide
an optimum sealing surface for the door bottom seal.
Product selection should be made when assessing the mandated
requirements listed in the AUS NCC and the Australian standard
AS 1905.1: Components for the protection of openings in fire-resistant
walls, Part1: Fire-resistant door sets, Section 5.5 Clearances
around Door Leaves. Specifiers will determine the suitability of
the information provided when selecting a Raven seal for their
Click for fire approved threshold plates.
